Inserts the specified element into this queue if it is possible to do so
immediately without violating capacity restrictions, returning
true upon success and throwing an IllegalStateException
if no space is currently available.

Inserts the specified element into the queue represented by this deque
(in other words, at the tail of this deque) if it is possible to do so
immediately without violating capacity restrictions, returning

Inserts the specified element into this queue if it is possible to do so
immediately without violating capacity restrictions, returning
true upon success and throwing an IllegalStateException

The Calendar class is an abstract class that provides methods
for converting between a specific instant in time and a set of calendar fields such as YEAR, MONTH,
DAY_OF_MONTH, HOUR, and so on, and for
manipulating the calendar fields, such as getting the date of the next
week.

An IllegalAccessException is thrown when an application tries
to create an instance (other than an array),
set or get a field, or invoke a method, but the currently
executing method does not have access to the definition of
the specified class, field, method or constructor.

Determines if the class or interface represented by this
Class object is either the same as, or is a superclass or
superinterface of, the class or interface represented by the specified
Class parameter.

Thrown if the Java Virtual Machine
tries to load in the definition of a class (as part of a normal method call
or as part of creating a new instance using the new expression)
and no definition of the class could be found.

Inserts the specified element into the queue represented by this deque
(in other words, at the tail of this deque) if it is possible to do so
immediately without violating capacity restrictions, returning
true upon success and false if no space is currently
available.

Pushes an element onto the stack represented by this deque (in other
words, at the head of this deque) if it is possible to do so
immediately without violating capacity restrictions, throwing an
IllegalStateException if no space is currently available.

Sets what the minimal days required in the first week of the year are;
For example, if the first week is defined as one that contains the first
day of the first month of a year, call this method with value 1.

Causes the currently executing thread to sleep (temporarily cease
execution) for the specified number of milliseconds plus the specified
number of nanoseconds, subject to the precision and accuracy of system
timers and schedulers.

Returns a set of keys in this property list where
the key and its corresponding value are strings,
including distinct keys in the default property list if a key
of the same name has not already been found from the main
properties list.

Causes the current thread to wait until another thread invokes the
Object.notify() method or the
Object.notifyAll() method for this object, or
some other thread interrupts the current thread, or a certain
amount of real time has elapsed.
